Dramas you wish you could watch again for the first time

Have you ever watched a drama so good that made you wish you could erase it from your memory so you can watch it again for the first time? There's nothing quite like watching an amazing drama for the first time that made you feel all kinds of emotions; full of mind-blowing and unpredictable plot twists or utterly hilarious (romantic) comedies and nostalgic feel-good ones that helped you go through difficult times, but you know that if you watch it again, the magic will be lost. The second time you watch it, you're going in with no surprises and the experience is never as good. Re-experiencing the whole journey is great but seeing it for the first time is priceless.
